Single channel vs dual channel RAM? HELP

[Pumba217]

So ive order the parts for my new pc (so stoked!) and i went with 1 x 8gb of corsair 1600 vengeance memory, the idea being that i could just get another 8gb stick and chuck it on no problem (as i initially wanted 16gb but you know dem prices). But i heard that sometimes installing separate kits such as two sets of 1x8 will not work, even if they're almost identical? Is this true or just bullcrap?

New PC Specs:
-i7 4770k

-MSI Z87 - G43

-120GB SSD

-Phantom 410
-GTX 770
-Corsiar CX-M600w
-1x8gb Corsair 1600 Vengeance RAM

 

Either a H100i or H80i in the near future for an overclock to about 4.4ghz

It's a bit of a crapshoot, sometimes they do sometimes they don't. The only way to be SURE is to use a 2x8GB kit since those would be rated together. Most of the time you should be good if you have the same model RAM though. So I would say get another 1x8 vengeance. Don't mix brands or anything like that.

they will work together if they are the same speed voltage and size

Brands mixing with the same timing and capacity + clockspeeds is fine.

I recall someone having trouble with that in the past though. Might have been something one-off but just in general I'd still make it a practice to stick with identical kits.
